Brazil was validated for the elimination of mother‑to‑child transmission of HIV in December 2025, in keeping with internationally accepted guidance, becoming the most populous country in the world to achieve this public health milestone.

To meet the validation criteria, Brazil reduced vertical transmission to below 2% and achieved coverage levels of above 95% for antenatal care, routine HIV testing, and timely treatment of pregnant women living with HIV, demonstrating the provision of high‑quality services for mothers and newborns, robust health information and laboratory systems, and a strong commitment to health for all.

In addition, the country received certification for the elimination of lymphatic filariasis as a public health issue following the completion of a serological survey and the preparation and review of the dossier submitted by Brazil to the external expert committee.

In both cases, PAHO played a central role by providing technical and methodological support to adapt tools to the national context, strengthen epidemiological surveillance, and consolidate robust evidence for certification. In addition, partners such as international organizations, subnational governments, and civil society also contributed through integrated strategies for care delivery, community education, and the expansion of service coverage.

This achievement reflects a comprehensive primary health care-based approach and demonstrates how sustained technical cooperation can translate into measurable results with lasting impacts on the health of mothers, newborns, and populations in situations of vulnerability, offering a replicable model for advancing disease elimination efforts in the Region of the Americas.
